Finally I managed to configure Huawei EC 152 [TataPhoton+] modem on
slackware-13(linux-2.6.36.2). It requires 'usb_modeswitch' package
which does the smart work of switching the device mode. These device
when plugged, will mount as a CD-ROM, and when ejected they will switch
to the modem mode. This technique avoid any extra drivers CD to be
shipped with a device as a result all the respective drivers(Windows &
Mac) are inside the device itself. For Windows it comes with own
dialer and an autorun file of ease of installation.

Latest Linux distributions like Fedora, Ubuntu and Mandriva
etc. includes usb_modeswitch package by default. User can directly
plug-in the device, the usb_modeswitch package will take care of
switching the device mode and you can dial-up the internet using
distribution's network manager.

I am using Slackware-13 with linux kernel ver 2.6.36.2 (Slackware-13.1
is released). Usb_modeswitch, wvdial(and wvstream) are not included in
Slackware by default, so you have to download its source or binaries
depend on the distribution you are using.

For those who are using Slackware distro's, Wvdial depends on
wvstream, both are available at
slackbuilds.org. Others
will have to search for binaries form distro website. I think their
package installer will do the same and install all the three packages
with their dependencies.

More information on usb_modeswitch can be found on
www.draisberghof.de/usb_modeswitch.
This website provide excellent introduction, detail explaination on
how to install, how to use, hardware support and
troubleshooting. Users can download the package in tar-ball or binary
format.

In this small tutorial, I describe, how I managed to configure and use
Huawei EC 152, Tataphoton+ modem. The procedure described is far more
generic apart for installing wvdial and wvstream packages using
slackbuild script.



########## TUTORIAL STARTS HERE ##########

Below is the output from /var/log/messages before installing
usb_modeswitch package, as you can see there is no trace of the device
identified as 'modem'. The device is identified as 'HUAWEI Mobile'
with respective idVendor and idProduct. As mentioned earlier it is
detected as scsi CD-ROM by usb-storage module.

/var/log/messages
Code:
kernel: usb 6-1: new full speed USB device using ohci_hcd and address 2

you can see similar output if your device is not switching


Installing usb-modeswitch and usb-modeswitch-data (.tar.bz2)


Package Versions

usb-modeswitch-1.1.7(dated:2011-02-27)
usb-modeswitch-data(dated:2011-02-27)
device_reference.txt(gzipped) from 2011-02-27 (for ref)

Requirement

tcl(for the wrapper script to work)
libusb-0.1.12 (already installed in slackware-13)

Installation:

for usb-modeswitch:

Code:
root# tar -xvjf usb-modeswitch-1.1.7.tar.bz2
root# cd usb-modeswitch-1.1.7
root# sudo make install
this will install the udev script, wrapper script, config files, man
pages and compile all the binaries.

for usb-modeswitch-data

Code:
root# tar -xvjf modeswitch-data-20110227.tar.bz2
root# cd modeswitch-data-20110227
root# sudo make install
this will copy usb-modeswitch.d/* in /etc/ [not in case of slackware]
you have to do it manually. This will also copy udev rules in
/lib/udev/rules.d/ and 'usb-modeswitch' file(bash script) in
/lib/udev/


If all goes well, you can see similar entry in your
/var/log/messages after plugging the device

The device has switched its Product ID from 0x1446 to 0x140b. If
your device is not switching it's mode, don't worry you have to
manually probe the device.

type:
usb_modeswitch -v <ur_idVendor> -p <ur_idProduct> -V
<ur_targetVendor> -P <ur_targetVendor> -s <NUM> -M <MsgContent>


You can download 'device_reference.txt' from www.draisberghof.de/usb_modeswitch.
Search for matching idVendor and idProduct. This file is pretty
descriptive and contains explaination to other flags. You must try all
possible configuration that is matching your idVendor and idProduct.

Example:
Code:
root# usb_modeswitch -v 0x12d1 -p 0x1446 -V 0x12d1 -P 0x140b -s 20 -M 55534243123456780000000000000011062000000100000000000000000000
